This recent photo provided by NASA and the European Space Agency, and captured by the Hubble Space Telescope, shows the deepest image of the universe ever taken in near-infrared light. The faintest and reddest objects in the image are galaxies that formed 600 million years after the Big Bang. No galaxies have been seen before at such early times. The new deep view also provides insights into how galaxies grew in their formative years early in the universe's history.

This image provided by NASA's Hubble Space Telescope Tuesday Dec. 15, 2009 shows hundreds of brilliant blue stars wreathed by warm, glowing clouds. The festive portrait is the most detailed view of the largest stellar nursery in our local galactic neighborhood. The massive, young stellar grouping, called R136, is only a few million years old and resides in the 30 Doradus Nebula, a turbulent star-birth region in the Large Magellanic Cloud (LMC), a satellite galaxy of our Milky Way. There is no known star-forming region in our galaxy as large or as prolific as 30 Doradus.

NASA's Hubble Space Telescope has broken the distance limit for galaxies and uncovered a primordial population of compact and ultra-blue galaxies that have never been seen before. The deeper Hubble looks into space, the farther back in time it looks, because light takes billions of years to cross the observable universe. This makes Hubble a powerful "time machine" that allows astronomers to see galaxies as they were 13 billion years ago, just 600 million to 800 million years after the Big Bang.

The data from Hubble's new infrared camera, the Wide Field Camera 3 (WFC3), on the Ultra Deep Field (taken in August 2009) have been analyzed by no less than five international teams of astronomers. A total of 15 papers have been submitted to date by astronomers worldwide. Some of these early results are being presented by various team members on Jan. 6, 2010, at the 215th meeting of the American Astronomical Society in Washington, D.C.

About

This blog has become a place where I post articles that I find related to global warming - causes and effects, as well as a few other topics - related or not.

Jellyfish are like poster-boys of global warming changes - jellyfish are one species of animal that are doing very well. The increased acidity of the oceans, warmer waters, the decrease in predators as fish and other wildlife decline have all favored jellyfish. They seem to thrive on the fertilizers that people have been washing into the seas. Most animals do not.

I also like to post discoveries - especially discoveries that are being made out in space as people are able to see farther and farther galaxies and nebulas and supernovas. Even though I don't think that people will ever go live any of those places - I just like knowing that they are out there. It's part of keeping in mind that the earth and it's inhabitants are such a small part of what is going on in the universe.

I have another blog with posts on art and artists - it's called M'S IMPRESSIONS.
